Update-SafeList

Use the Update-SafeList cmdlet to update the safelist aggregation data in Active Directory. Safelist aggregation data is used in anti-spam filtering in Microsoft Exchange Server 2010. EdgeSync replicates safelist aggregation data to computers that have the Edge Transport server role installed.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "SafeList aggregation" entry in the Transport Permissions topic.

The Identity parameter specifies the Outlook user mailbox from which you want to collect safelist aggregation data. Valid input for this parameter includes the following values:

GUID

Distinguished name (DN)

Domain\Account

User principal name (UPN)

LegacyExchangeDN

SmtpAddress

Alias

Confirm

Optional

System.Management.Automation.SwitchParameter

The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.

EnsureJunkEmailRule

Optional

System.Management.Automation.SwitchParameter

The EnsureJunkEmailRule parameter specifies whether to force the junk e-mail rule to be turned on for the mailbox if the rule isn't turned on already.

Note:

The junk e-mail rule can only be created after the user logs on to the mailbox. If the user has never logged on to the mailbox, this parameter can't turn on the junk e-mail rule.

IncludeDomains

Optional

System.Management.Automation.SwitchParameter

The IncludeDomains parameter specifies whether to include the sender domains specified by users in Outlook in the safelist aggregation data. By default, domains specified by the senders aren't included.

In most cases, we don't recommend that you include domains because users may include the domains of large Internet service providers (ISPs), which could unintentionally provide addresses that may be used or spoofed by spammers.

Type

Optional

Microsoft.Exchange.Management.RecipientTasks.UpdateType

The Type parameter specifies which user-generated list is updated to the user object. Valid values for this parameter are SafeSenders, SafeRecipients, and Both. The default value is SafeSenders.

Important:

In Exchange 2010, the safelist aggregation feature doesn't act on Safe Recipients List data. We don't recommend running the Type parameter with the SafeRecipients or Both values.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.

This example updates safelist data for all user mailboxes in your Exchange organization. By default, the Exchange Management Shell is configured to retrieve or modify objects that reside in the domain in which the Exchange server resides. Therefore, to retrieve all the mailboxes in your Exchange organization, you must first set the scope of the Shell to the entire forest using the Set-AdServerSettings cmdlet. For more information, see Set-AdServerSettings.

To activate the options to include safe domains, or to change the maximum values for the default settings, you must change the msexchangemailboxassistants.exe.config file. Specifically, the following settings and values can be changed in the appsettings section of the msexchangemailboxassistants.exe.config file:

Setting

Value

IncludeSafeDomains

The value for this setting can be True or False.

UpdateInterval

By default, the value for this setting is 15 minutes. This setting can have a value from 15 minutes through 1 day.

TestUpdateInterval

TestUpdateInterval is used in test environments. This setting can have a value from 10 seconds through 1 hour.

MaxSafeSenders

3*1024

MaxSafeRecipients

2*1024

MaxBlockedSenders

By default, the value for this setting is 500. The maximum value is 1000.

For example, the settings in the appsettings section of the msexchangemailboxassistants.exe.config file may be as follows:
